From 2006 until 2007, he was the head football coach at Ridgeway High School in Memphis, Tennessee. From 2003 until 2005, he was the defensive coordinator of the Memphis Tigers football program. He transformed the Tigers defense from a unit that ranked near the bottom statistically in defense, to a top 25 defensive unit. Prior to coaching at Memphis, he was the defensive coordinator at Mississippi State from 1996 to 2002. In 1995, he served as the defensive coordinator at Arkansas, helping the Razorbacks win their first SEC Western Division championship that season.
